Water storage container (not furnished).
The water
storage container is a source of treated potable
water and is connected by flexible hose to the water
chiller for cooling.
Start run valve.
The start run valve directs the

the engine the start run valve must be in the start
position.
In this position the water by-passes the
blending valve.
After a few minutes turn the start
run valve to the run position.
Water is now
circulated through the blending valve.
Blending valve.
The thermostatically controlled
blending valve controls the flow of water for
tempering warm water from the storage container with
cool water from the evaporator to provide a constant
load to the evaporator heat exchanger inlet.
Water pump.
The water pump circulates the potable
water through the evaporator jacket for cooling or
through the blending valve for recirculating as
